Fog

Fog was added to ROBLOX on December 9, 2011. It is supposed to be just like fog in reality, and the color and distance of the fog can be modified by the Lighting service. It can be used to make games more realistic and atmospheric.

On January 7, 2015, fog was added for players with their graphics quality set to 7. It was heavily criticized, one reason being that official fog had 'ruined' scripted fog. Many players on the forum have asked ROBLOX to add a feature to make fog optional instead of mandatory. Instead, as a response to the protests, ROBLOX removed the feature.
